Abstract
A system for carrying out gas chromatography/mass spectroscopy (GC/MS) on gasses trapped in glass solidified from molten glass includes a glass sample vacuum chamber having a gas inlet, a gas outlet, and an introduction port for receiving the glass sample; a crushing tool for crushing the glass sample; a gas sample vacuum chamber disposed in downstream fluid communication with the glass sample vacuum chamber; a supply of carrier gas in fluid communication with the glass sample vacuum chamber; a GC/MS analyzer in downstream fluid communication with the gas sample vacuum chamber; an injector in fluid communication between the GC/MS analyzer and the gas sample vacuum chamber and for injecting the gas sample into the GC/MS analyzer; a gather valve in fluid communication between the glass and gas sample vacuum chambers; and a booster in fluid communication with the gas sample vacuum chamber.
